Hi Friends,
From past few months I am into aquascaping, previously I had T5 lighting setup which I changed to PLL recently.
I Keep lights on for 6 Hours total with timings at morning 7.30 to 10.30 and at night 8.30 to 11.30
I want to know is my photo period is right or not.
My tank specifaications are as follows

I wont suggest for the split lighting. As when you start the lighting period, the photosynthesis might not occur immediately. It will take time for the photosynthesis to occur. And you switch off the light in 3hrs. So the photosynthesis is not occurring continuously.

In addition, the lighting is only 2 WPG.

Which plants are melting off?

How old is the setup? More than one month, then it is supposed to be 8hrs per day.

The photoperiod should be 8hrs a day and if you provide it at a stretch then would be better as mentioned by Shelly.

Are you using any reflectors for your lights?? if you are not using any then a lot of it is going waste. A good reflector with the lights is also very important. That CFL wont provide you any penetration as your tank is 18" tall.

A major reason for melting of plants is lack of nutrients, but as you dont have a CO2 setup (a pressurized one) it will be a problem if you increase the dosage of nutrients as it may invite algae. In case you decide to increase the dosage better ensure consistent supply of CO2.

Now I have increased photoperiod to 7 Hrs, but stll splited in two timings morning 8.00 to 10.00 and evening 6.30 to 11.30 for now.
Will see results ( any algae problem or heat problem ) and keep continuos 8 Hrs after two weeks.
Is it OK???

After 3-4 months, do you still feel that the split timings are working good for you? (2 hours in the morning and remaining hours in the evening)
You have mentioned the results of 1 day.
But over a period of few months, what is the result?
